If you prayed 'Asr and then remembered that it was the time for Zuhr, is it permissible for you to change your intention during the prayer?

The questioner : Changing the intention in prayer. I intended to pray 'Asr while it was the time for Zuhr, and then I remembered that it was the time for the Zuhr prayer. Is it permissible to change the intention during the prayer?

The Shaykh : It invalidates the prayer.

The questioner : It invalidates the prayer.

The Shaykh: Yes.

The questioner : A voluntary prayer.

The Shaykh : And he intends, and he intends the correct intention, and he says the takbir of entering into prayer.

The questioner : Praise be to Allah.
